BACKGROUND: Replantation is the most indicated procedure for traumatic dental avulsion, but it invariably results in a greater or lower degree of root resorption. The outcomes of these cases can be affected by some well-known factors. Because studies have shown the importance of the innate and acquired immune response in the mechanisms involved in the resorption of bone tissues, an endeavor was made to verify if such an influence applies to dental resorption. METHODS: Fifty-seven avulsed, endodontically treated teeth were assessed in the Endodontics Clinic, Pontifical Catholic University of Paraná. Follow-up of the replanted teeth included periodical clinical examinations and radiographs, in accordance with the control rules of the International Association of Dental Traumatology. The evaluation of atopy was based on the patient's personal and family history in conjunction with the skin-prick test for five allergen extracts. RESULTS: Of the 46 teeth with a favorable outcome, 33 (71.74%) were in atopic patients, and 13 (28.26%) were in non-atopic patients. Of the 11 teeth with an unfavorable outcome, four (36.36%) were in atopic patients, and seven (63.64%) were in non-atopic patients; a greater prevalence of unfavorable prognoses occurred in non-atopic patients. CONCLUSION: The outcome after 1 year for avulsed and replanted teeth is more favorable in atopic patients.
